Microsoft 365 Outages Disrupt Teams and SharePoint Services Globally

Microsoft 365 Services Impacted by Global Outages

In a recent incident on July 23, 2026, a massive outage primarily affected users in North America, with Downdetector recording 2,403 reports by 11:11 AM ET, significantly higher than the typical baseline of 29. During this event, SharePoint accounted for 78% of user complaints, followed by Excel at 11% and the Microsoft 365 Admin Center at 6%, according to BleepingComputer.

Scope of Technical Disruptions

The disruptions have manifested in various technical failures across the Microsoft 365 suite. During recent service issues, users reported the following:

* Microsoft Teams: Degraded chat functionality, including images failing to load, and difficulties in joining or creating meetings and calls. * SharePoint Online: Users encountered Something went wrong error messages. * Microsoft 365 Admin Center: Services loaded slowly or failed to open entirely. * OneDrive: Access was reported as intermittent. * Power Automate: Flows failed to load. * Copilot Chat: Users experienced intermittent delays or failures in query actions. * Microsoft Loop: Inability to open or load pages.

Microsoft has directed administrators to specific incident tracking numbers within the Microsoft 365 admin center, such as MO1437424, to monitor the status of these investigations.

Regional Outages and Root Causes

Outages have frequently been linked to networking and configuration updates. In a regional disruption affecting Japan and China, Microsoft identified a routing fault within its service infrastructure. Engineers mitigated the issue by rebalancing traffic across backup systems, eventually restoring services. Microsoft confirmed that the outage in that region was limited to the Asia-Pacific area and stated there was no indication of a cyberattack, as reported by Indiatimes.

In other instances, global connectivity issues were traced back to Wide Area Network (WAN) updates. During one such event, Microsoft acknowledged that a network configuration change caused connectivity problems between clients on the internet and Azure, as well as between services in datacenters. The company successfully rolled back the update to initiate service recovery, according to Petri.

Recovery and Operational Impact

The impact of these outages extends to business operations and, in some cases, public proceedings. For instance, a previous Teams outage in the Asia-Pacific region delayed court proceedings in Australia, where users were unable to access the service for meetings.

Microsoft typically manages these events by monitoring service telemetry and deploying mitigation steps. In the case of the North American outage on July 23, 2026, the company actively tested new mitigations to bring services back online. For regional issues, such as those in New Zealand, Microsoft advised that affected calls and meetings might need to be ended and restarted once recovery is observed to ensure functionality returns to normal, as noted by Nzherald. The company continues to monitor service health through its official status channels to confirm when mitigating actions have successfully resolved the impact for users.
